Comfort material: The calf sleeves are made of high-quality plastic foam, which is both elastic and breathable to improve comfort and reduce sweating. The outer shell of the shin guards is made of strong plastic material with a layer of foam inside to reduce external impact forces, effectively protecting calf muscles, reducing sports injuries, and providing comprehensive protection for your tibia. Anti-slip design: The mini leg pads offer an ideal fit and contour for optimal comfort. The socks hold them securely in place, preventing movement or shifting during exercise, ensuring a tight, comfortable fit that minimizes sliding and friction between the shin pads and skin, enhancing performance without discomfort. Super lightweight and compact: The mini shin pads measure 8 x 5 cm (3.14 x 1.96 in), making them smaller than standard shin guards. This design ensures they stay securely in place during play, eliminating concerns about slipping or falling off. Perfect match: These shin guards are compatible with football socks and standard athletic socks, offering no discomfort and no impact on performance. They provide reliable lower leg protection and are suitable for beginners and experienced athletes who play football. Protective effect: Ideal for various physical activities such as football, running, tennis, racquetball, gym workouts, walking, and weightlifting. Helps support recovery from calf muscle injury, arthritis, tendinitis, sore muscles, and post-operation rehabilitation.
